postfix安装出错
OS: RHEL5.4
错误提示如下：
postfix-install: Error: "postfix" needs an entry in the passwd file.
Remember, "postfix" needs a dedicated user and group id.
make: *** [install] error 1
解决方法如下：
groupadd postfix -g 1000
groupadd postdrop
useradd postfix -u 1000 -g postfix -G postdrop
然后回到安装目录，重新make install.
